Name: Gutierrezia sarothrae / Bouteloua gracilis Dwarf-shrub Grassland Reference: NatureServe Biotics 2019 Description: This grassland association is known to occur in the mountains of northern New Mexico. It most commonly occurs on gently rolling mesatops, terraces, and occasionally along canyon footslopes (4-10% slopes) on sites with moderate solar exposure. Elevation ranges from 1670 to 2230 m (5470-7310 feet). Soils are primarily fine-textured Alfisols derived from eolian or slope alluvium deposits over rhyolitic tuff residuum, or occasionally well-developed Mollisols derived from pumice slope alluvium. The ground surface is characterized by bunchgrass patches in a matrix of exposed soil and litter with little or no gravel or rock. The vegetation within this association is characterized by abundant to luxuriant grass cover dominated by <i>Bouteloua gracilis</i> (30-60%). Other common grasses may include <i>Elymus elymoides, Pleuraphis jamesii</i>, and <i>Sporobolus cryptandrus</i>. While forbs are typically poorly represented, the ruderal subshrub <i>Gutierrezia sarothrae</i> can be dominant and reach up to 30% cover. Ruderal succulents such as <i>Opuntia phaeacantha</i> or <i>Opuntia polyacantha</i> may also be common. Trees are absent or represented by scattered individuals of <i>Juniperus monosperma</i> or <i>Pinus edulis</i>, mostly as seedlings or saplings.  Accession Code: urn:lsid:vegbank.org:commConcept:34142-{6E83C970-D653-48AF-B216-AFD1A840A99E} Plot-observations of this Community Concept: 0
